Dell PowerEdge VRTX - VDR93: Virtual Disk 0 bad block medium error is cleared.

So I have a VRTX enclosure, 25 SFF version, with one Shared PERC8 controller and 1 expander backplane module.

All firmwares are up to date, however, I am not sure what is going on here.

I'm using Hitachi HUC109045CS600 hard drives (450GB, SFF SAS). I put them in a RAID 10 and initialize, however, every time I initialize and it completes or during initialization this message in the "Recently Logged Storage Events" is showing:

BAT1003	Wed Mar 21 22:00:22	2018The battery on Shared PERC8 learn cycle has completed.
VDR93	Wed Mar 21 20:37:39 2018	Virtual Disk 0 bad block medium error is cleared.
VDR23	Wed Mar 21 20:37:37 2018	Initialization of Virtual Disk 0 has completed.
BAT1002	Wed Mar 21 19:49:17 2018	The battery on Shared PERC8 learn cycle has started.
BAT1027	Wed Mar 21 19:49:17 2018	The battery on Shared PERC8 completed a charge cycle.
VDR11	Wed Mar 21 19:45:48 2018	Virtual Disk 0 has started initializing.
VDR3	Wed Mar 21 19:43:41 2018	Redundancy normal on Virtual Disk 0.
VDR98	Wed Mar 21 19:43:39 2018	Virtual Disk 0 has switched active controllers. Its active path is now through Chassis Integrated RAID 1.
VDR4	Wed Mar 21 19:43:24 2018	Virtual Disk 0 was created.

 

The message I am concerned with is VDR93, Virtual Disk 0 bad block medium error is cleared. I've seen this come up on virtual disks that was also preceeded by a message saying "A SCSI device experienced an error, but may have recovered" but in this instance, I'm not seeing that message.

I'm not really sure what to make of the message, I've googled it but it's still unclear to me if it means that some underlying physical disk is experiencing errors or something like that?

Can someone clarify? The storage logs do not reference a particular physical disk. These are not Dell branded drives however as far as I know they're not special purpose fiber channel drives or drives from an EMC, NetApp, or IBM disk array.

Thank you.
